Broadcasting dcd server crash. Unable to connect socket

[rocex]

This problem has bothered me for a long time. Other computers still exist on the latest version of the software. I saw it, too https://github.com/Pure-D/code-d/issues/123 , according to what's said here, it still hasn't been solved.

I'm also getting basically this same exact error. Im on Windows 10. Same error code: -1073741819

[WebFreak001]

some DUB libraries or user code can cause this (there are some stack overflow errors when using too-nested static if / else if / else if / ...

ddbc is a known cause for this.

[vanceism7]

Ah that makes sense. It started happening to me after I installed the hibernated package, probably because I don't actually have the driver libs installed. Thanks for the explanation

[WebFreak001]

no, it's actually because of how some code is structured, which crashes DCD due it going out of memory when iterating over its tree representation due to the large call stack. Installing things won't fix this, we need to flatten the AST tree in libdparse somewhat to better fix this, or just throw more memory at it, which is imo not a great solution (when doubling memory usage it will just break again when the code size of the problematic area is doubled)

[vanceism7]

Yea lol, just realized I did end up having those dependencies installed and my code started compiling and running, but the dcd was still crashing.

we need to flatten the AST tree

Sounds like a doozy lol
